CBS gave the group a television variety show (entitled Tony Orlando and Dawn) from the summer of 1974, after The Sonny and Cher Comedy Hour ended its run, until December 1976. The show was in the same vein as its predecessor (with sketches featuring sarcastic back-and-forth banter between Orlando, Hopkins and Vincent, similar to the sarcastic dialogue between Sonny and Cher) and became a Top 20 hit.
They are most famous for "Tie a Yellow Ribbon" & "Knock Three Times"!
